Conference Presentations

In this talk, the importance of the search potential for heavy neutral leptons (HNLs), i.e. heavy non-SM neutrinos, are presented. [...]

This will be a review on existing Higgs theory predictions for an e+e- Higgs/top/EW factory, especially with respect to the preparations of the theory part of the Physics Briefing Book for the European Particle Physics Strategy Update. This brings in the focus on the needed improvements to match the envisioned experimental precision at CEPC. [...]

Since the early 2000s, the discovery of integrable sectors in the AdS/CFT correspondence has established a deep connection between string theory, quantum groups, and exactly solvable models. In this framework, the R-matrix in specific representations encodes the scattering properties of interacting strings through quantum group symmetries. [...]

The hexagonalisation technique arose in the context of N=4 SYM theory to address the tessellation of the effective world-sheet describing three-point functions of single trace operators. Despite its apparent technical difficulty, exploiting the knowledge of all its ingredients at finite 't Hooft coupling one can perform some non-trivial limits, like the strong-coupling one. [...]

The precise determination of the Higgs self-couplings is an essential task for understanding electroweak symmetry breaking and probing physics beyond the Standard Model (SM). The calculation of two-loop corrections is important to provide a critical test of the perturbative stability, especially in the case of large one-loop corrections that can occur in scenarios with extended scalar sectors. [...]

The next-to-minimal supersymmetric extension of the Standard Model (NMSSM) belongs to the most prominent, best motivated and experimentally widely tested beyond-SM extensions. For a meaningful interpretation of the experimental results and in order to be able to pin down the model underlying nature from the theory side, precise predictions for observables and parameters are crucial.
